Test Center guide to browser security
Chrome, Firefox, Internet Explorer, Opera, and Safari have different security advantages and shortcomings. More important than the browser you choose, however, is how you maintain and use it.Follow @rogeragrimes
Opera is a solid browser that deserves more market share in the PC world. It has impressive security granularity, good anti-DoS handling, strict Extended Validation certificate handling, and many unique features. Its lack of market share means it hasn't been as tested as Internet Explorer and Firefox, but it has been involved in fighting many found vulnerabilities.
On the downside, Opera doesn't support DEP (Data Execution Prevention), ASLR (Address Space Layout Randomization), or ECC (Elliptical Curve Cryptography) ciphers. These deficiencies need to be corrected before its use can be more highly recommended. Even now, I invite readers to check out Opera. I think many people will be pleasantly surprised.

Apple Safari 3.2.1
Apple's Safari browser has many good features, but lacks security granularity and zones. It has good pop-up blocking, good local password protection, and a surprisingly accurate anti-phishing filter. Unfortunately, DEP is disabled, something that needs to be corrected. Safari has the weakest cipher support, failing to offer AES ciphers, 256-bit keys, or ECC ciphers.
Safari always automatically prompts the user before downloading files, and it prevents some high-risk files from being executed before downloading. Safari has good default cookie control. It is one of only two browsers in this review (the other is Chrome) to prevent all writes by third-party cookies by default, which is a nice privacy bonus. Although local password protection is strong, Safari had the weakest remote password handling of the bunch. Safari is a great-looking browser but a mixed bag with respect to security.
